My built micro is kind of heavy, it is my first attempt at DIY multicopter. I ordered the Syma X1 boards and motors before I ordered a WL 202 that could be here any day. I got the MJX rotors for it. I figure if I don't like my build, I can always use the parts on other quads. Sorry for posting this in the X1 thread, it should go in the DIY thread, but it is at least 50% an X1.

The stock USB cable that comes with the X1 is a simple, non-intelligent (as in dumb) cable. It does not know when to stop charging.

I am assuming that the charging is stop by a OCP circuit hidden inside the stock battery. I'm assuming because I didn't break open the cap.

But I know that I'm working with a dumb cable, because I used it to charge a hobby grade Lipo, while I monitored the voltage of the battery under charge. The USB cable just happy charged away. My Lipo under test went passed 4.2 volt and the USB light didn't turn off (it suppose to go off an full charge and stop charging). It kept charging until it reached 4.30v when I aborted the experiment.

Mine were nearly identical to this set. (More on that later) the circuit has a resistor in the battery box and runs off in the same voltage range as the little Lipo. Mine were red and, ok, to be honest, they were shaped like hearts, (I found them in a drawer and they were forgotten by the wife, don't judge me) but a set of side cutters trimmed them nicely into little plastic LED nubs exactly like the ones being sold here.

The power wire they are strung on is mildly stiff and moldable with a thin nonconductive coating. I used little dots of hotmelt to affix them around the frame and at the ends of the booms. There were enough lights to circle the frame and put at least two on each boom. If you don't want as many, just trim the line when you are done. They are wired in parallel. I ended up not using 8 lights from the end of the string.

If you are a gram counter, I imagine you are having an aneurism right now, but for night hoonage, this fits the bill nicely and flies great.

Don't tell my wife. I've been using her USB charger in the living room for a month without any drama to charge two 600mah batteries. Trust me, if one of those things had cooked off next to her, I would have heard all about it.

Forever.

When the light goes out, I unplug it. (it isn't even warm.) ill use a sack from now on and budget for a 1s charger.

I also read your comment in the other thread. I don't know what makes your USB light go off. I could not duplicate it. I also used 600 mAh Lipo. Mine just kept charging and charging. Had I not aborted the experiment, I didn't know what would happen.
